Questions Before Purchasing

Looking at the pro version here and have a few questions
1) WordPress Multisite compatible?
2) Does it offer any advanced embed features like this plugin does? (https://wordpress.or...-for-wordpress/) - or is your plugin just specifically for YouTube galleries? I see 'advanced embed controls' but just want to make sure that's the same thing.

3) Where are premium add-ons, are those only viewable from inside the Wordpress Dashboard?
